I use ’tmux’ on anything that runs it, from FreeBSD, macOS and Linux.
One some of Linux servers, noticably openSUSE ones, when I connect to them via SSH, I would receive the following warning:
...
Have a lot of fun...
warning: Could not set up terminal.
warning: TERM environment variable set to 'tmux-256color'.
warning: Check that this terminal type is supported on this system.
warning: Using fallback terminal type 'ansi'.
What worse is that, when I switch to root account, the backspace key doesn’t work correctly. For example, hitting backspace will produce a space instead.
How can I fix this? By setting the variable TERM='xterm'.
➜ export TERM='xterm'
➜ ssh tc2

Some also suggested to set th set the default value in the ~/.tmux.conf as the follwoing:
set -g default-terminal "xterm"
And how did I find this out? Of course, by searching for similar problem on the internet. Full credit goes to the owner of the article below.
